Code of dht11 interfacing with arduino code for dht11 temperature and humidity sensor.
Arduino dht11 temperature humidity sensor code.
In this tutorial you will learn how to use this sensor with arduino uno.
In this project we will use the ky 015 arduino dht11 temperature humidity sensor and display it to the arduino ide serial monitor.
Include dht h including the library of dht11 temperature and humidity sensor define dhtpin 2 selecting the pin at which we have connected dht11 define dhttype dht11 selecting the type of dht sensors dht dht dhtpin dhttype.
The dht 11 is a digital output relative humidity and temperature sensor.
The materials are here as follows.
In this tutorial we will learn how to use a dht dht11 version temperature and humidity sensor.
The room temperature humidity will be printed to serial monitor.
It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin.
It measures both moisture and air temperature.
Dht11 temperature and humidity sensor with arduino.
Learn how to use temperature and humidity sensor with arduino how to connect dht11 or dht22 temperature and humidity sensor to arduino how to program arduino step by step.
Display humidity and temperature on the serial monitor.
In this section we ll build a simple project with the arduino that reads temperature and humidity and displays the results on the serial monitor.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
Again we will be using a library specifically designed for these sensors that will make our code short and easy to write.
10k ohm pull up resistor.
Arduino uno read best arduino starter kits.
Arduino uno any uno will work i have a geekcreit uno.
Here we also display those readings on an lcd display.
It s accurate enough for most projects that need to keep track of humidity and temperature readings.
Void setup serial begin 9600.
To complete this tutorial you need the following components.
This project is really simple and shouldn t take us very long.
